Read full descriptionHide full description
Immrs is an immersive sensory experience that brings live visuals, spatial sound, and haptics together. Press to accelerate into the center. Drag to bend the space, trace a circle to rotate it, and tilt your device for subtle parallax. When you let go, motion and sound ease out with natural momentum. Highlights • Real-time GPU visuals with distinct motion and textures • Depth, speed, and distortion driven by touch pressure and movement • Haptics synchronized with layers and transitions • Spatial sound that reacts to every visual state • A full-screen vertical feed • Automatic quality, battery saver, and Reduce Motion support • Photosensitivity protection, limited color shifts, and complete haptic or sound controls • No account required Every core visual is generated live on your device without video streaming. Input data is not sent to an external server, and the core experience works offline. How access works Five minutes of access are refreshed every day based on your local date. You can choose to finish a 30-second rewarded ad to add 30 minutes for that day. Remaining and rewarded time do not roll over; each new day starts with the included five minutes. Immrs does not present automatic full-screen ads. Immrs Unlimited The monthly subscription unlocks unlimited usage time and removes the bottom banner. There is no free trial. Your App Store displays the price for your storefront, and you can manage or cancel the subscription in your account settings. Immrs does not use rapid full-screen flashes or white strobe effects. If motion feels uncomfortable, enable Photosensitivity Protection or Reduce Motion and take a break.

Start the engine and move the throttle to hear and see the revs change. Explore inline, V and rotary engines in 3D. • A range of engines Explore Inline-3 Compact, Inline-4 High-rev, Inline-4 Turbo, Inline-5 Turbo, Inline-6 Twin, V6 Even-fire, V8 Low-rev, V10 High-rev, V12 Grand and Rotary Twin-rotor. Drag to rotate the engine, then open the expanded view to inspect moving parts such as pistons, connecting rods, the crankshaft and rotors. • Views and close-up inspection Choose a top, side, front or default view, and use two fingers to move or zoom the view. In the expanded view, you can slow the motion down 12× or see through the fixed parts to watch the parts inside, while the sound and revs stay at real speed. Piston engines also show the combustion glow and exhaust heat. • Four gearboxes Choose a 5-speed manual, 6-speed manual, 8-speed automatic or 7-speed dual-clutch. Use the gear controls and clutch, brake and throttle pedals for the selected gearbox. Follow the engine state on the tachometer and gear display. With a manual gearbox, revs build more heavily in higher gears and you can feel the lever engage each gear. The clutch pedal shows engaged, slipping and open zones, and you can turn on a large shift lever in Settings. • Drive modes and launch control Comfort, Sport, Sport Plus and Custom drive modes change the throttle response, automatic shift points and exhaust valve sound. For Custom, choose throttle response, shifting and exhaust valve separately in Settings and save them. Sport Plus also offers launch control. • Exhaust and sound settings Change the exhaust and tuning in Settings and compare the sound from idle to high revs. Audio is generated in real time from the engine's behavior; it does not play recordings of real vehicles. • Ads and access Start the default inline-six engine without watching an ad. Other engines can be previewed while stopped; a rewarded ad is offered when you first try to start one. A confirmed reward grants 24-hour access to that engine on this device. Press Start again after the ad closes. Passes are saved separately for each engine. Expiry does not interrupt an ongoing session, but returning to or reopening the app restores the default engine if the pass has expired. The default engine remains available if an ad cannot open or a reward is not confirmed. Banner ads may appear at the bottom of the screen. No account or sign-in is required. The app interface is available in 17 languages, including English, Korean, Japanese and Chinese. The engines are original designs and do not reproduce any specific manufacturer or vehicle.
